COVID-19 and Hearing Loss
Reports of hearing loss and tinnitus (ringing in the ears) have been associated with COVID-19 for some patients. A scientific review published recently in the International Journal of Audiology summarizes these trends.
Researchers from the University of Manchester conducted a systematic review of available scientific literature regarding COVID-19 and associated hearing loss and tinnitus published through December 2020. Based on stringent criteria for meta-analysis and bias risk, the authors rejected 850 records while 28 case reports and 28 cross-sectional studies met their inclusion criteria. Their analysis of the data revealed that 7-15% of adults diagnosed with COVID-19 reported auditory (ear/hearing) and/or vestibular (balance) symptoms. The most common symptoms
- Tinnitus (ringing in the ears) – studies show ringing in the ears lasting weeks or months after the infection had cleared.
- Hearing difficulties
- Vestibular issues such as dizziness or vertigo.
